Controls

Option

Description

Flight Camera Control type

This setting determines whether the flight camera is used and how it is accessed. The flight camera uses the W, A, S, and D keys to dolly and pan the camera, similar to how standard FPS controls work. W and S dolly the camera in and out, while A and D pan, or strafe, the camera side to side. When active, this overrides any hotkeys using these controls, including toggling show flags.

Option

Description

Use WASD for Camera Controls

The flight camera and WASD controls are always active.

Use WASD Only When Right Mouse Button is Held

The flight camera and WASD controls are only active when the RMB is pressed.

Never Use WASD for Camera Controls

The flight camera and WASD controls are never active.

Grab and Drag to Move Orthographic Cameras

If enabled, clicking the Left or Right Mouse Buttons and dragging the mouse in an orthographic viewport will scroll the camera. Essentially what this means in practice is when you click and drag, the scene will move with the mouse. With this disabled, the scene moves opposite of the mouse.

Orthographic Zoom to Cursor Position

If enabled, zooming in the orthographic viewports will be centered around the mouse cursor. When disabled, zooming is centered on the center of the viewport.

Link Orthographic Viewport Movement

If enabled, all orthographic viewports will be linked to focus on the same position. So moving the camera in one orthographic viewport will cause the other orthographic viewports to follow. When disabled, all viewports can be navigated independently.

Aspect Ratio Axis Constraint

Determines which axis of the perspective viewport is used to control the field of view (FOV) to maintain the aspect ratio when resizing.

Option

Description

Maintain Y-Axis FOV

The Y-Axis (vertical) is used to determine the FOV.

Maintain X-Axis FOV

The X-Axis (horizontal) is used to determine the FOV.

Maintain Major Axis FOV

The larger of the two axes is used to determine the FOV.

Mouse Scroll Camera Speed

Determines the speed at which the perspective camera moves when navigating with the mouse.

Clicking BSP Enables Brush

If enabled, clicking on a Brush surface selects the brush and Ctrl + Shift + Click selects the surface. When disabled, the opposite is true; clicking selects the surface and Ctrl + Shift + Click selects the brush.

Update BSP Automatically

If enabled, Brush geometry rebuilds automatically when brushes are moved or modified in the viewport. When disabled, geometry must be rebuilt to see the changes.

Preserve Actor Scale on Replace

If enabled, replacing Actors will respect the scale of the original Actor. Otherwise, the replaced Actors will have a scale of 1.0.

Privacy

The Editor in Unreal Engine 4 (UE4) collects usage data to help Epic continually improve UE4. There are three types of data that the Editor can collect:

Crash reports - generated when an error causes the Engine to crash.

Bug reports (also known as ensures) - generated when an issue causes the the project to reach a certain unforeseen state, but does not cause a crash.

Usage data (also known as analytics) - a collection of data about the user.

When the Engine crashes, a crash report is generated. Crash reports automatically offer you a choice of whether or not to send crash data to Epic.

Disable Bug Reports

For bug reports, you can disable data collection in the Privacy category of Editor Preferences. Follow these steps to disable bug reports.

In the menu bar, click Edit > Editor Preferences.

In the Editor Preferences dialog, scroll down to the Privacy category.

Click Bug Reports. In the right pane, under Options, the default setting is Send unattended bug reports.

If you do not want bug reports sent to Epic, click Don’t Send.

Disable Usage Data

Usage data primarily consists of aggregated or anonymized information that does not directly identify you as an individual user. However, this usage data may also include the following:

User's IP address

User's Internet Service Provider (ISP)

User's Continent, Country and City

User's Epic Account ID

User's project name

If you are concerned about privacy and want to opt out of usage data collection, you can change the setting in the Privacy category of Editor Preferences. Follow these steps to disable usage data collection.

In the Editor Preferences dialog, scroll down to the Privacy category.

Click Usage Data. In the right pane, under Options, the default setting is Send Usage Data.

If you do not want usage data sent to Epic, click Don’t Send.
